Based on the proposed multi-core network processor heterogeneous operating system software framework and P-SPL data plane programming model, this paper proposes an implementation of iSCSI initiator. Experimental result proves that the implementation based on the multi-core network processor heterogeneous operating system software framework has better performance on throughput and response time than the implementation based on Linux. In 6 GE ports experiment environment, the new implementation gets a maximum of 180 MB/s read and write throughput improvement a
